5 years agonss: simplify initialization of struct file in map_file()

nss: simplify initialization of struct file in map_file()

It's not necessary to initialize ->fd at the beginning of map_file() as
the call to open(2) will overwrite it anyway.

Also adapt a check for a valid file descriptor. Although POSIX states
that open(2) returns -1 on error, there is no reason to hard-code this
constant. Instead, check for any negative value.
